We at TRAFFESSIONALS think ROUNDABOUTS are one of the best engineering examples of where ART meets SCIENCE. Some of our more interesting designs include:
EDSEL STREET / VITASOVICH AVENUE (2010)
This dual-lane compact roundabout is located between two large shopping centres in the Henderson town centre in Auckland, and is a form of Compact Urban Roundabout with raised platform zebra crossings on each approach road. Compared to the traffic signal alternative which was initially proposed, this solution gives improved safety and operation for all road users including cyclists and pedestrians.
WAIMUMU ROAD / TRIANGLE ROAD (2009)
This C- Roundabout (or Cyclist – Roundabout) in West Auckland has a special geometry with deliberately narrow traffic lanes to ensure driver speeds are around 30 km/hr or less, and is a form of Compact Urban Roundabout. This dual-lane design developed in New Zealand allows on-road cyclists to safely mix with vehicle traffic, and novice cyclists are provided with a peripheral shared path to cross as pedestrians if they so wish.
WOODLANDS PARK ROAD / HUIA ROAD (2009)
This was a challenging topographical location in the Waitakere Ranges of Auckland, with approach roads at skewed and offset orientations. The solution was well appreciated by the local community, and particularly for children wanting to cross this rural road with limited sightlines.
METCALFE ROAD / MUNROE ROAD (2008)
This single-lane compact roundabout was adroitly placed between two off-set side roads, a railway crossing, and a sweeping downhill bend on a fringe rural road area in West Auckland. It well addressed a location with previous traffic delays and safety problems.
WOODGLEN ROAD / WOODVALE ROAD (2007)
This single-lane compact roundabout in a residential area was built for less than $30K at a previous crash black spot on a main road bend, and uses approach islands for speed control with a flush-level central island. Vehicle tracking was able to be maintained for up to semi-trailer vehicles in the southbound direction.
